MEANS FOR SUPPLYING LIQUID HYDRGCARBON TO CABBUBETEB-S.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed April 12, 1917. Serial No. 161,627.

To all whom it may concern:

Be it known that 1, JOHN THOMAS GRAHAM, subject of the King of Great Britain, residing at 13 Chapel street, Halstead, Essex, England, engineer, have invented certain new and useful Improvements in Means for Supplying Liquid Hydrocarbon to Carburetors, of which the following is a specification.

This invention relates to means for supplying liquid hydrocarbon to carbureters, of the type consisting of a cup or dipper pivoted, in the tank, to a lever operated by means of a rod and cranks, said cup depositing the hydrocarbon into a funnel connected to the supply pipe of the carbureter.

It has been found in use that the pivoted cup tends to swing and thus lose some of its contents and also while swinging the lip of the cup is liable to catch on the edge of the funnel and thus temporarily check or stop the machine.

The object of this invention is to provide an improved device of this type which will obviate the above-mentioned disadvantages.

According to this invention the cup or dipper is pivotally mounted in a cradle which is itself pivoted to one end of a distortable parallelogrammatic frame.

The invention will now be described with reference to the accompanying drawings in which Figure 1 is an elevation of one form of the cup or dipper mounted in the petrol tank, Fig. 2 is a plan of the cup or dipper and Fig. 3 is an end view of same.

The parallelogrammatic frame consists of a pair of rods a, 7), the extremities of one side being pivoted at c, 0 to the tank (Z, the pivots 0, c are arranged vertically one above the other. The extremities of the other side are pivotally connected at 6, 6 to the cradle f in which the cup 9 is pivotally mounted. The pivots 6, 6 are also arranged vertically one above the other.

The pivot h of the cup 9 is disposed at the bottom thereof and well forward of the center line in order that the cup may always rest on the seat 3' pivoted in the cradle f.

.The rod a is extended in order that it may be connected by suitable rods to an oscillating part of the machine.

The rods a, b, may be of any desired shape.

Suitably positioned above the funnel is of the supply pipe m of the carbureter is a loosely mounted pawl 41, which is adapted to contact with the inside portion of the lip of the cup when said cup is raised and tilt same,

A well 0 is provided in the bottom of the tank and so disposed that the cup may dip into same and pick up the hydrocarbon therefrom.

The cradle f is preferably L-shaped, the top and bottom extremities of which are pivoted to the ends of two rods and the forward extremity has the cup pivoted to it.

The cup 9 may be of any desired shape and is preferably formed with a lip. It has been found, however, that a rectangular shaped cup serves very well.

WVith a device made in accordance with this invention the cup is retained horizontal in all positions and is prevented from swinging when being raised, but can be tilted easily by contact with the depending pawl on reaching its highest position. As soon as the cup is moved away from the pawl it returns to its seat in the cradle.

What I claim is 1. Means for supplying predetermined quantites of liquid hydrocarbon to carburet ers comprising a reservoir for the liquid hydrocarbon, a well in the base of said reservoir, a distortable parallelogrammatic frame disposed in the reservoir and having a cradle pivoted to one end thereof, a cup or dipper pivotally mounted in the cradle, and means to tilt said cup in the cradle, the cup being adapted to pick up quantities of hydrocarbon from the reservoir and discharge the same to the feeding means 0.. the carburetor.

2. Means for supplying predetermined quantites of liquid hydrocarbon to carbureters comprising a reservoir for the liquid hydrocarbon, a well in the base of the reservoir, a cradle movably mounted in relation to the reservoir, a cup or dipper pivotally mounted in the cradle, and means mounted In testimony whereof I have hereunto set in said reservoirand operable to contact my hand in presence of tWo subscribing Wit 10 with a portlon of the 11p of the cup When nesses.

the cup is raised and tilt said cup, the cup T r being adapted to pick up quantities of hy- JOHL FHOMAS GRAHAM drocarbon from the material of the reservoir WVitnesses: and discharge the same to the feed means ALBERT CoNs, of the carbureter.
